Direct discharge without effective treatment will cause serious damage to the ecological environment. Therefore, wastewater treatment technology has become one of the core research directions in the field of environmental protection.

[0003] In current wastewater treatment equipment, impurities in the wastewater automatically settle inside the sedimentation tank during operation. This prevents the equipment from achieving rapid sedimentation, thus affecting the wastewater treatment process. Summary of the Invention

The drive gears drive the rotating tubes to move the installed stirring rods, thereby stirring the wastewater inside the centrifuge.

[0007] Preferably, a control panel is installed on the outer wall of the electrolytic cell.

[0008] Preferably, mounting grooves are provided on the inner walls at both ends of the electrolytic cell; the electrolysis assembly includes an electrolysis power supply, which is placed on the outer wall of the electrolytic cell, and the two ends of the electrolysis power supply are connected to the anode electrolysis plate and the cathode electrolysis plate respectively through power supply lines, and the anode electrolysis plate and the cathode electrolysis plate are respectively placed inside the mounting grooves.

[0009] Preferably, the electrolytic cell has slag discharge grooves at both ends of its bottom, and an electrolytic impurity sealing mask is installed at the bottom of the slag discharge groove. An electrolytic impurity conveying roller is installed inside the electrolytic impurity sealing mask. A conveying motor is provided on the outer wall of the electrolytic impurity sealing mask, and the conveying motor is connected to the electrolytic impurity conveying roller at one end. The ends of the electrolytic impurity conveying rollers at both ends are connected to each other through a synchronization component, which is located on the outside of the electrolytic impurity sealing mask. The synchronization component includes a synchronization wheel, which is located at the end of the electrolytic impurity conveying roller, and the synchronization wheels are connected to each other through a synchronization belt.

[0010] Preferably, the end of the electrolytic impurity sealing mask is provided with an impurity discharge component, the impurity discharge component includes an impurity discharge pipe, the impurity discharge pipe is placed at the bottom end of the electrolytic impurity sealing mask, and a first control valve is installed on the impurity discharge pipe.

[0011] Preferably, a wastewater supply assembly is also provided on the side wall of the electrolytic cell. The wastewater supply assembly includes a main supply pipe, which is located outside the electrolytic cell and has several branch supply pipes installed on it. The branch supply pipes pass through the electrolytic cell and are inserted into the centrifuge tube. A connecting pipe is also provided at the end of the main supply pipe.

[0012] Preferably, the centrifuge drum is provided with a discharge hopper at the bottom, and a discharge assembly is installed at the bottom of the discharge hopper; the discharge assembly includes a discharge pipe, which is connected to the discharge hopper, and a second control valve is installed on the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses a centrifuge tube inside an electrolytic cell to centrifuge and precipitate impurities, which are then discharged into the electrolytic cell. The precipitated wastewater is then electrolyzed using an electrolysis assembly. This not only makes efficient use of the electrolytic cell space but also increases the versatility of the device.

[0018] This invention achieves synchronous rotation of the turbine by using a rotation drive component, which enables the centrifuge cylinder to rotate and centrifuge simultaneously for sedimentation. This achieves efficient utilization of the power source and synchronous operation of the equipment, and simplifies control.

[0019] This invention introduces flocculant into the bottom of a centrifuge tube through a flocculant inlet via a rotating tube. A rack and pinion reciprocating frame drives a drive gear to rotate reciprocally, which in turn drives a stirring rod to rotate reciprocally through the rotating tube. This stirring method generates a more complex flow field and stronger shear force within the limited space of the centrifuge tube. This not only avoids the entanglement phenomenon caused by excessively high local flocculant concentration, but also promotes the collision of fine particles and the growth of flocs, thus creating more favorable conditions for subsequent centrifugal sedimentation and significantly improving pretreatment efficiency and sedimentation effect.

However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] See Figures 1-10 In this embodiment of the invention, a wastewater treatment device includes an electrolytic cell 1, on which an electrolytic assembly 14 is installed. The electrolytic assembly 14 is placed on the side walls at both ends of the electrolytic cell 1 and is used to electrolyze and settle the wastewater after centrifugal sedimentation treatment inside the electrolytic cell 1.
